heterogeneous catalyst

Postby Sukanya Mohapatra 2G » Sat Mar 14, 2020 1:58 pm

Why are the most common heterogeneous catalysts finely divided or porous solids?

Well it makes sense to me that since a solid heterogeneous catalyst cannot be blended with the reactant perfectly, then we probably want to at least maximize the surface area.

Most heterogeneous catalysts are solids, and in order to maximize catalyst-substrate interaction it needs to be porous or finely divided.

Because it wants to maximize the surface area of the catalyst, so it is able to be involved in more places.
